VALVE.

To all whom it may concern:

Be it known that I, CHARLES 'J. SIDDALL, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certainnew and useful Improvements in Valves, of which the following is a specification.

T his invention relates to improvements in valves.

My improved valve is particularly adapted and is illustrated and described by me herein as a valve for gas burners. My invention, however, is applicable and desirable for vari one other uses.

lhe main objects oi my invention are: first, to provide means for lighting and extinguishing simultaneously plurality of gas burners; second, to provide an improved valve mechanism adapted to be operated at a distance; third, to provide an improved valve mechanism for gas burners which is adapted to flash the pilot and maintain the same in its flashed condition as long as desired; and, l'ourth, to provide an improved valve mechanism embodying these advantages which is very simple and economical in structure and one which is not likely to get out of repair when in use.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in. the accompanying drawing, forming a part of this s; ocification, in which:

Figu re 1 is a detail elevation ol' a structure embodying the features of my invention; 2 is an enlarged vertical section. taken on a line corresponding to line 22 of Figs. 1, 3 and a Fig. 3 is a vertical section taken on a line corresponding to line 33 of Figs. 2 and i; Fig. at is a horizontal section taken on line corresponding to line ll of Fig. 2; and 5 is a horizontal section taken on a line corresponding to line 55 of Figs. 2 and ln the drawings, similar characters oi reience refer to similar parts throughout the several views, and the sectional views are taken looking in the direction oi, the little arrows at the ends of the section lines.

deferring to the drawing, I have shown my improved valve in connection with the gas Specification of Letters Patent.

burners l. The pilot burner 2 is of the flash pilot type. The valve easing at is provided with an inlet passage 5, a main burner discharge passage 6 and a pilot burner passage 7 The inlet passage is connected tothe main burner assage by a chamber 8 and with the pilot va lve passage by the chamber 9. The valve seats 10 and 11 project into these chambers 8 and 9 respectively. The valves 12 and 14 are disk-like or are in the form of diaphragms, forming partitions across the chambers '8 and 9 and closing against the valve seats, thereby controlling the delivery of the gas through these passages. A bypass passage 15 is provided i'or connecting the inlet and the pilot valve passage 7 to maintain the constant pilot flame. A suitable valve as the needle valve 16, is provided for adjusting this by-pass.

The chambers 8 and 9 on the outside of the valve are adapted to contain fluid. ln the upper part of the casing I provide a iluid chamber or reservoir 17. This is connected with the pilot valve chamber 9 by means of the passage 18, the two chambers forming in effect one chamber. The fluid chamber is connected through the passage 19 to what I have herein designated as a trap and which, as illustrated, consists of the trap passage 20, opening into which is a fluid passage 21. The passage 21 opens into the trap passage above the level of the liquid in the liquid chamber and is connected at its lower end with the main valve chamber below its valve or diaphragm. The passage 21 is preferably a tube and projects up through the trap passage, as illustrated. This fluid passage serves as a fluid column for operating the valve.

The fluid chamber is preferably provided with a diaphragm 22. The air passage 23 is connected to the fluidehamber on the outside of the diaphragm, or, when the diaphragm is omitted, above the level of the fluid therein. To the air passage I connect a device for producing suction 0r pressure, a bulb 24. being illustrated for this purpose. In practice, a bulb may be used, but where a large numb or of valves are to be controlled, a suitable operating mechanism would be provided. Th operating device 24 is provided with a vent opening 25, through which the fluid chamber may be connected with the atmosphere, the object of which will clearly appear from the state ment of the operation of the device.

For convenience in manufacture, I preferably form my improved valve casing of hori zontal sections 26, 27 28 and 29, as is clearly illustrated in the drawing. By this means I can easily form the passages and chambers by means of coring the parts in casting, turning or drilling the same. The section 29 is provided with a nipple portion 30, into which the gas burners 1 may be threaded and the section 26 with a nipple portion 31 into which the gas sup ly pipe, as 32, may be threaded. The va ves or diaphragms are preferably of leather and are supported and clamped in position by bolts, as 33, passing through the valve casing sections, this not only forming suitable packings for the joints of the sections, but effectively supporting the valves in place. I prefer-bly use for this purpose leather, although other materials would undoubtedly be found satisfactory.

With the parts assen'ibled and connected in the normal position,-that is, with the valve closed, the operation of my improved valve is as follows: When it is desired to light the burners, suction is created in the fluid chamber, which draws the fluid, or a portion thereof from the pressure chamber and the main valve chamber through the trap into the reservoir chamber, relieving the pressure on the valve 12, so that it opens to admit gas to the main burner. This also opens the pilot valve 11 so that the gas passes t ough the valve to flash the pilot. On account of the trap connection between the main burner valve chamber and the fluid chamber, the fluid drawn from the main burner valve chamber cannot return. When the suction is broken in the fluid chamber, as by opening the vent 25, the pilot valve 11 closes so that the length of time which the pilot valve is open may be gaged by maintaining the suction. When it is desired to close the main burner valve, pressure is produced in the fluid or reservoir chamber, which forces fluid into the main valve cham her or fluid column to close the main valve. It will be obvious that the valves are under complete control and will be maintained in their adjusted position. I preferably use mercury as the fluid, as that possesses such Weight that a comparatively small amount is all that is necessary to produce a column of suflicient height to overcome any gas pressure against the valve.

My improved valve, while it is particularly adapted and illustrated herein in con nection with gas burners, is adapted for use in other relations. By the use of these valves, a lighting system may be operated to simultaneously light or close all of the valves, even though some of the lamps may be at a distance. The pilot can be maintained a suflicient length of time to insure the lighting of the burners,that is, it can beheld flashed until the air has been driven out of the pipes and gas supplied to the burners to insure then igniting. As the pilot is automatically closed on the breaking of the suction, it is also under perfect control.

I have illustrated and described my improved valve mechanism in detail in the form preferred by me on account of structural simplicity and economy. I am, however, aware that it is capable of very great variation in structural details without de- )arting from my invention, and I desire to be understood as claiming the same specifically, as illustrated, as well as broadly.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
